ISO1176T/35T/3086T Evaluation Module
This document describes the ISO1176T/35T/3086T Evaluation Module (EVM). It is used to evaluate the
ISO1176T PROFIBUS™ Transceiver, the ISO35T RS-485 Transceiver, or the ISO3086T RS-485
Transceiver. Because the devices are similar transceivers, and the printed-circuit board is the same for all
three EVMs, this manual can be used for all three devices.

The EVM can be used to evaluate device parameters while acting as a guide for board layout. The board
allows for the connection of 50-

coaxial cables via QuietZone connectors. It also provides easy
connection points for oscilloscope probes. Banana jacks are provided for connection of a dc power supply.
These features provide the designer with a tool for evaluation and the successful design of an
end-product.
